• When pressure is relieved, tool resets automatically
• Ball bearing signal mechanism assures repeatability and accuracy, and eliminates speed sensitivity errors
• Tools are calibrated in the right hand direction only, accuracy is +/- 3% between 20% and 100% of the range, and a factory calibration tape is supplied with each wrench (left hand calibration is available on special order)
• Emits an audible click and an impulse when torque setting has been reached
• Recalibration is done externally, so there's no need to disassemble the wrench
